I need multiple RS422 receiver in one PCB board. (only support receiver is enough, can support transceiver is OK.) Hope to find small package chip to save the PCB board. Now I find ADM268x, with some questions here.
1, Does this chip have isolated DC/DC power, only need to add 5VDC or 3.3VDC at the logic side?
2,Does this chip can be used as RS422 transceiver?
3,My request is: RS422 interface, isolation voltage is 1kVrms, data rate is ≥500kbps. Do you have other chips can save space? Multiple receiver in one chip is better.
1, Yes. We have isolated power integrated, only need to add 5VDC or 3.3VDC at the logic side.
2, Yes, it can be used as RS422 transceiver.
3, You can choose ADM2582, which isolation is 2.5kV, and it’s same as ADM2682 except isolation voltage. But we don’t have isolated multiple transceivers in one chip. But I think this one is best for you. Because it can help you to save the space of isolated power. How many RS422 do you need in one board?
